Great choice to widen your walk! You've asked a couple of times about the pavers. I think that if you can find brick that matches the color of your house bricks that it will add a consistency that is appealing. It may be difficult to find a gray paver that looks good with the gray of your house. I like bluestone, and it might work color-wise, but it also has a reputation for being slick in wet weather. You are also making a good choice to avoid yews if you have deer issues. I have plenty of deer, but also plenty of alternate food sources in our woodlands, and the one plant that the deer consistently nibbled down to stubs when I had them was yews. One other thing I noticed is that some of your current plants (such as the hydrangea behind the J. maple along the garage or the plants between the walkway and the garage) are planted too close to the building so that the plants are misshapen. When you replant near the building, be sure plants such as shrubs or large perennials have at least a foot or two from the expected ultimate size of the shrub and the building so that the plant isn't leaning out or rubbing up against the building once it is grown.

beef up those posts w/cedar. you could wrap what you have. Something along this size. (or wrap them in the white,,,either will work) I would paint the trim around your windows with a darker color (charcoal, black, bronze/brown) to give it some contrast. Can you look on Craigslist for another door (if you're on a budget)? something with some glass, perhaps? For instance, w/this door color, I'd do all of the trim and fascia in the same tone. stain the cedar posts a bit darker, paint the bricks the same color as your siding and perhaps tile that cement porch. It would look like a whole new space.

IMO a better view of the whole front of the house would be helpful . I like the light but hate the storm door I really hides most of whatever door you choose and really not needed IMO if you go with a good insulated door and if you need the screen go with a phantom screen. You have already chosen to mix metals since IMO the light fixture and the house #s should have been the same color. I need to also see the patio right now all this is to me is a mish mash of stuff that I can't see working together.

This brings back memories as I lived in the North Dallas area in the 60s. Your trees are wonderful. I would focus on making significant changes to the landscaping to update the exterior of your home. I do think getting a more MCM front door and painting it an accent color—teal or a bright green would be interesting and draw attention to it. Get rid of the wrought iron gate and put in one with cleaner lines. Get a new porch light in a rectangular shape. If you search this site for MCM exterior I’m sure you will find examples that appeal to your taste. Definitely get rid of the shutters! If the pole light in the yard isn’t functional and you don’t need it, I would remove it. Get rid of the ground cover under the large tree on the right side of the house. All of the landscaping is so mature it would be best to start over with a fresh design plan. You can work with one of the local nurseries to design and install new plantings. I think re-landscaping like some of the pictures Beth H shared would make a huge statement — just decide if you like the more structured looks or curving beds since either one would look fine with the house.
